"What happens in Washington... is the president is not a representative of the political establishment class, so for whatever reason the people have made a decision that they want to eject him," he told George Stephanopoulos of ABC News on Sunday.

"I think there are elements inside of Washington, also inclusive in the White House, that are not necessarily abetting the president's interests or his agenda."

However, he said the president needed to bring in "more loyalists" in order to carry out his agenda.

Anthony Scaramucci (C) was fired after an audio recording was released in which he insulted adviser Steve Bannon (L) and then-Chief of Staff Reince Priebus

The Wall Street financier criticised the influence of Mr Bannon and the right-wing Breitbart News website, which he helped to launch.

He suggested the president needed to move more towards the mainstream and moderates in order to push through "a very successful legislative agenda".

Mr Scaramucci made a lasting impact in his short term in office, triggering a White House shake-up that saw the departure of both Mr Priebus and spokesman Sean Spicer.
